Hi Richard,
Steve and I go camping and riding all year round, I have had a look at the campsite mentioned in the thread and it looks like it is open April till October. So it looks like next year unless someone knows of one nearby that is open all year around?
But to be fair, the last thing you want when it is cold is to get soaking wet from puddles and such if you cant`t get warm and dry again, so it might be best left till the weather is warmer again.
